Promote schema and canonicalizer out of history; add EvidenceModel (T06)

Verified the three published hashes reproduce byte for byte before promoting
anything, then moved the schema, canonicalizer and vectors into governed assets.
history/20260909-initial-exploration/ is untouched and stays the provenance
record.

- schemas/, informed_decision/, tests/vectors/ populated; the reference
  canonicalizer's ad-hoc __main__ block replaced by a real
  `python -m informed_decision` entry point.
- tests/test_canonicalize.py — 20 tests, all green. Published vectors, all four
  isolation properties, canonical-form round-trip, key sorting, and a provenance
  test asserting the governed fixtures have not drifted from history/.
- docs/specs/EvidenceModel.md — the two hashes, the split and why it exists, the
  four isolation properties, the presentation record, the bundle, and the
  relationship to audit-core.
- pyproject.toml, Makefile.

One test of mine was wrong on first run: it scanned for ", " to assert no
insignificant whitespace, which fires on prose inside a brief. Replaced with a
canonical round-trip comparison, which is the property actually meant. The
canonicalizer was correct.

EvidenceModel leads with what the model does NOT claim — no proof of
comprehension, no proof of reading (deliberately, since the alternative is
surveillance), no survival of a compromised surface, and audit-core's inherited
bound that a hash chain cannot prove a record was never sent.

T06 stays progress: the SCOPE.md rewrite is gated on the T02 ruling.
